🐛 Source Snowflake: Fixed parsing of extreme values for FLOAT and NUMBER data types

[irynakruk]

What

Connector provides wrong values for a datatype:

1. For all Data Types for Fixed-point Numbers in Snowflake the range of values is all integer values from -99999999999999999999999999999999999999 to +99999999999999999999999999999999999999 (inclusive), but returned NULL. The MIN and MAX values are Long extreme values.
2. FLOAT - NaN, inf, -inf values is returned as NULL, but should be mapped to Double NaN / POSITIVE_INFINITY / NEGATIVE_INFINITY

How

Added SnowflakeSourceOperations class with two overrided methods: putDouble and putBigInt, which contain specific data type handling for Snowflake.
